How to Start an LLC in Indiana (Step-by-Step Guide)

Forming an LLC in Indiana requires filing Articles of Organization with the Indiana Secretary of State and paying a $95 filing fee online ($100 by mail). Online filings through the INBiz portal are typically processed in less than one business day, making Indiana one of the fastest states for LLC formation.

Follow these steps to start your Indiana LLC in 2026.

How to Start an LLC in Indiana (6 Steps)

Step 1: Name Your Indiana LLC

Your LLC name must be distinguishable from other business names registered in Indiana. The name must include “Limited Liability Company,” “LLC,” or “L.L.C.” as a designator at the end.

Search the Indiana Secretary of State’s business entity database to check availability. This free search tool shows all registered entities so you can verify your desired name isn’t already taken or confusingly similar to an existing business.

If you want to secure a name before filing, you can reserve it for 120 days by filing a Name Reservation application ($20 online). This is optional but useful if you need time to finalize your business plan, secure financing, or gather formation documents.

Indiana naming rules:

• Must include an LLC designator (“Limited Liability Company,” “LLC,” or “L.L.C.”)
• Cannot be the same as or deceptively similar to an existing entity registered in Indiana
• Cannot include words suggesting it’s a bank, insurance company, or government entity without proper authorization
• Cannot contain language implying the LLC is organized for an unlawful purpose
• Cannot use restricted professional terms without meeting specific licensing requirements

Tips for choosing a strong LLC name: Check if a matching domain name is available and search for the name on social media platforms. Also search the USPTO trademark database to avoid potential infringement issues with nationally registered trademarks. If you plan to operate under a different name than your LLC name, you’ll need to register a “Doing Business As” (DBA) name separately.

Step 2: Choose a Registered Agent

Indiana requires every LLC to have a registered agent with a physical street address in Indiana. The registered agent receives legal documents (including lawsuits), state notices, and official correspondence on behalf of your LLC.

You have three options for your registered agent:

• Be your own registered agent: Free, but you must have an Indiana physical address (not a PO box), be available during normal business hours, and your name and address become public record.
• Appoint a trusted individual: They must be an Indiana resident with a physical address and available during business hours to accept documents.
• Hire a professional registered agent service: Provides privacy, reliability, document forwarding, and compliance alerts. Costs $39-$299/year.

Our top recommendation is Northwest Registered Agent ($39/year), which also handles LLC formation for $39 + the $95 state fee. Northwest provides a physical Indiana address, scans and forwards all legal documents digitally, and sends compliance reminders before your biennial report is due.

Step 3: File Your Articles of Organization

File Form 49459 (Articles of Organization) with the Indiana Secretary of State. You can file online through INBiz (Indiana’s online business portal), by mail, or in person at the Secretary of State’s office in Indianapolis.

Filing details:

• Filing fee: $95 (online) or $100 (by mail or in person)
• Online filing: INBiz portal (recommended — same-day or next-business-day processing)
• Processing time: Less than 1 business day (online), 2-3 weeks (by mail)
• Payment: Credit/debit card (online), check payable to Indiana Secretary of State (mail)

Information required on the Articles of Organization:

• LLC name (with the LLC designator)
• Registered agent name and physical street address in Indiana
• Principal office address
• Whether the LLC is member-managed or manager-managed
• Name and address of at least one organizer
• Duration of the LLC (perpetual is the standard choice)
• Effective date (can be the filing date or a future date)

Member-managed vs. manager-managed: In a member-managed LLC, all owners share in daily business decisions. Manager-managed is better when you have passive investors or want a designated person running operations while other members remain hands-off. Most small Indiana LLCs choose member-managed.

Why INBiz? Indiana’s INBiz portal is one of the most user-friendly state business filing systems in the country. It handles LLC formation, annual reports, tax registration, and other business filings all in one place. Processing times are typically same-day or next-business-day, making it ideal for entrepreneurs who need their LLC approved quickly.

Step 4: Create an Operating Agreement

Indiana doesn’t legally require an operating agreement, but having one is strongly recommended. An operating agreement is an internal document that establishes the rules for how your LLC operates, including ownership structure, profit distribution, management responsibilities, and what happens when members join or leave.

Your operating agreement should cover these essential areas:

• Member ownership percentages and initial capital contributions
• Voting rights and decision-making procedures
• How profits and losses are distributed among members
• Management structure and day-to-day authority
• Procedures for admitting new members or handling departing members
• Transfer restrictions and buyout provisions
• Meeting requirements and record-keeping procedures
• Dissolution procedures and winding up

Even single-member LLCs should create an operating agreement. It reinforces the legal separation between you and your business entity — which is essential for maintaining your limited liability protection — and most banks require one to open a business bank account.

Step 5: Get an EIN

Apply for an Employer Identification Number (EIN) through the IRS website. An EIN is your LLC’s federal tax ID number — essentially a Social Security number for your business. The application is free and takes about 15 minutes online.

You need an EIN to:

• Open a business bank account (required by virtually all banks)
• Hire employees and set up payroll
• File federal and state tax returns
• Apply for business credit cards, loans, and lines of credit
• Register for Indiana sales tax (if applicable)

We recommend getting an EIN even if you’re a single-member LLC without employees. It protects your Social Security number and adds professionalism to your company’s dealings with clients and vendors.

Step 6: File Your Business Entity Report and Register for Taxes

After forming your Indiana LLC, you need to handle two important ongoing requirements:

Business Entity Report (Biennial Report): Indiana LLCs must file a Business Entity Report every two years with the Indiana Secretary of State. This is sometimes called a biennial report.

• Filing fee: $32 (online through INBiz) or $50 (paper filing)
• Due date: Every two years, during the anniversary month of your LLC’s formation
• Filing method: Online through the INBiz portal (recommended — $18 cheaper than paper)
• What it covers: Confirms or updates your LLC’s registered agent, principal office address, and member/manager information

Tax Registration: If your LLC will sell taxable goods or services in Indiana, you’ll need to register for a Registered Retail Merchant Certificate (Indiana’s sales tax permit). You may also need to register for withholding tax if you hire employees. Register for both through INBiz.

Indiana LLC Costs

Total first-year cost: $95-$399 (depending on whether you use a registered agent service). Indiana’s ongoing costs are very low — you only file a Business Entity Report every two years ($32 online), making it one of the most affordable states for long-term LLC maintenance. See our complete guide to LLC costs by state for a full comparison.

Want to save money? Using an LLC formation service like Northwest ($39 + $95 state fee = $134 total) is far cheaper than hiring an attorney ($500-$2,000). For most straightforward LLC formations, a formation service handles everything you need.

Indiana LLC Taxes

Indiana has a low flat income tax rate of 2.95% for 2026, one of the lowest flat rates in the country. However, you’ll also need to factor in county income taxes, which vary by location. Here’s the complete breakdown:

• State income tax: 2.95% flat rate on all taxable income (for 2026). This rate has been gradually decreasing — it was 3.23% in 2023, 3.05% in 2024, 3.0% in 2025, and 2.95% in 2026, with further reductions planned.
• County income tax: Additional 0.5%-3.38% depending on the county where you live. This is in addition to the state rate, so your effective combined rate could be anywhere from 3.45% to 6.33%.
• Franchise tax: None. Indiana does not impose a franchise tax on LLCs.
• Sales tax: 7% state rate (no local sales taxes). Indiana has a simple, uniform 7% sales tax statewide with no local add-ons.
• Self-employment tax: 15.3% on the first $168,600 of net self-employment income (2026 federal rate), plus 2.9% Medicare tax on amounts above that threshold.
• Federal taxes: Standard pass-through taxation — the LLC itself doesn’t pay federal income tax. Profits pass through to members’ personal returns.

Tax tip: Indiana’s declining state income tax rate (currently 2.95% and scheduled to drop further) makes it an increasingly attractive state for LLC owners from a tax perspective. The uniform 7% sales tax statewide (no local variations) also simplifies compliance compared to states with complex local sales tax structures.

Annual Requirements for Indiana LLCs

To keep your Indiana LLC in good standing, you must meet these ongoing requirements:

• Business Entity Report: $32 (online) or $50 (paper), filed every two years during the anniversary month of your LLC’s formation with the Indiana Secretary of State through INBiz.
• State tax returns: LLC members report their share of LLC income on their personal Indiana income tax returns (2.95% state rate plus county taxes). Multi-member LLCs also file a partnership return.
• Maintain a registered agent: Must have a registered agent with an Indiana physical address at all times. Update the Secretary of State through INBiz if your agent changes.
• Sales tax compliance: If your LLC sells taxable goods or services, collect and remit 7% sales tax to the Indiana Department of Revenue.

Frequently Asked Questions

How long does it take to form an LLC in Indiana?

Online filing through the INBiz portal is typically processed in less than one business day, making Indiana one of the fastest states for LLC formation. Filing by mail takes 2-3 weeks. Online filing is strongly recommended for both speed and cost savings ($95 online vs. $100 by mail).

Does Indiana have a franchise tax?

No. Indiana does not impose a franchise tax on LLCs. Your main tax obligation is the state income tax (2.95% flat rate for 2026) plus your county income tax (0.5%-3.38% depending on location). Indiana also does not charge an annual business entity tax, making it one of the more tax-friendly states for LLC owners.

Can I form an Indiana LLC if I live in another state?

Yes. You can form an Indiana LLC regardless of where you live. You’ll need a registered agent with a physical address in Indiana. However, if you primarily do business in another state, you’ll need to register your Indiana LLC as a foreign LLC there, which means double fees and filings. For most small businesses, forming an LLC in the state where you operate is simpler and more practical. See our how to start an LLC guide for more on choosing the right state.

Does Indiana require an operating agreement?

No, Indiana doesn’t legally require an operating agreement. However, we strongly recommend creating one for every LLC. It defines member roles and responsibilities, protects your personal liability by reinforcing the legal separation between you and your business, and most banks require one to open a business account. Without an operating agreement, your LLC is governed by Indiana’s default LLC statute, which may not align with your preferences.

How often do I need to file a report in Indiana?

Indiana requires a Business Entity Report every two years (biennial), not annually. The report is due during the anniversary month of your LLC’s formation. Filing online through INBiz costs $32, while paper filing costs $50. The biennial schedule means less paperwork and lower costs compared to states that require annual reports. Just make sure to file on time — failure to file can result in administrative dissolution of your LLC.
